Abstract: As a typical dynamic disaster in deep mining,rockburst poses a serious threat to the safe‐ ty production and engineering progress of mines. Therefore,accurately assessing the rockburst risk,espe‐ cially the characteristics of rockburst occurrence,is crucial for the safety of deep mining operations. This study focuses on the Shangzhuang mining area,Canzhuang Gold Mine,and systematically analyzes the rockburst risk during deep mining. Various methods including rock mechanics tests,the Hoek-Brown strength criterion for parameter conversion,hydraulic fracturing for in-situ stress testing,and numerical simulation were employed to provide foundational data for rockburst risk assessment. Historical data were used to simulate the ground pressure distribution,and the tendency of rockburst occurrence was further ex‐ plored.The results indicate that rockburst occurrence is closely related to mining depth and the stress state of the rock mass. Slight block rockfalls are likely to occur at a depth of approximately 700 m in the hanging and footwalls of the Shangzhuang mining area,while a similar risk of rockbursts exists in the point pillars at a depth of around 500 m. Furthermore,the simulation results show that as mining depth increases,the tendency for rockbursts becomes significantly stronger,particularly in regions of stress concentration, where the rockburst risk further intensifies. By analyzing the occurrence patterns of rockbursts,recommen‐ dations for optimizing mining design and implementing preventive measures are proposed,offering valu‐ able references for mine safety production and rockburst prevention.
